馃摝 Published to pub.dev: dart_tui 2.0.0

This major release hardens the terminal runtime, ports the selected Bubble Tea
capabilities through P9, and removes the temporary compatibility APIs so the
package has one clear model, styling, and program-configuration path.

Breaking changes

  • Models: removed the TeaModel alias. Extend or implement Model
    directly.
  • Keys: removed the LegacyKeyMsg alias. Use KeyPressMsg for press
    events or the shared KeyMsg base type.
  • Styles: removed the raw ANSI TuiStyle helpers. Use immutable Style
    values such as const Style(isBold: true).render(text).
  • Program configuration: removed ProgramOptions and the parallel
    programOptions / programSettings parameters. Program, forms, prompts,
    and gum helpers now accept one List<ProgramOption> named options. Use
    withAltScreen(), withTickInterval(...), withHideCursor(...), and
    withLogFile(File(...)) for the former struct fields.

Bubble Tea parity

  • Added declarative terminal colors, native progress reporting, keyboard
    options, and view-level mouse callbacks.
  • Added Kitty progressive-keyboard negotiation and modern key press, repeat,
    and release events.
  • Added Unicode Core negotiation plus shared grapheme-aware terminal width
    handling across input, styling, and rendering.
  • Expanded the viewport with gutters, per-line styles, search highlights,
    filling, and horizontal navigation.
  • Added dynamically sized, visually wrapped textarea behavior.
  • Added multi-stop, scaled, and callback-driven progress colors.
  • Added rich underline styles, OSC 8 hyperlinks, and ANSI-state-safe layout
    operations.
  • Added explicit dark/light component style factories and immutable
    suggestion, cursor, and viewport introspection APIs.

Runtime correctness and security

  • Made cell diffs width-aware for CJK, emoji, and other double-width
    graphemes, while reducing cell parsing from quadratic to linear work.
  • Made declarative cursor position, shape, blink, and color reach the terminal.
  • Correctly consume OSC, DCS, APC, PM, and SOS control strings without leaking
    payload bytes into rendered cells.
  • Made Program.kill() wake idle programs and restore terminal state.
  • Corrected Unicode capability-report semantics and sanitized window-title OSC
    payloads.
  • Preserved cumulative SGR and OSC 8 hyperlink state in CellRenderer, made
    multi-grapheme input edits atomic, and restored viewport line styles around
    highlighted spans.

Release quality and tooling

  • Added real-PTY tests for kill, external cancellation, resize,
    suspend/resume, and terminal restoration.
  • Centralized alternate-screen, cursor, focus, paste, and mouse transitions in
    one terminal-mode state machine shared by both renderers.
  • Aligned local and CI analysis on one clean repository-wide boundary.
  • Made plain Dart the default across Make targets, examples, VHS tapes, and
    website source mirrors; FVM remains an optional override.
  • Refreshed meta, lints, and test constraints to their current resolvable
    releases.
  • Moved README previews to the hosted documentation assets and excluded local
    GIF binaries from the pub archive.

Documentation and examples

  • Upgraded the documentation site to patched Next.js 16.3.0 with dedicated
    audit, typecheck, and production-build CI.
  • Refreshed the component gallery, guides, API snippets, and all 60
    tape-backed example previews for the 2.0 API.
